Abstract: Abstract of the Disclosure A scouring device in which a shaped scouring pad is held up into a rigid skirt portion of a pad holder, the skirt portion being generally concave and having downwardly extending projections, by a securing member which has a washer-like member at its base and a stem extending up to a flattened axial portion which goes through a slit in the holder and then is turned about 90°.  This, together with projections on the bottom of the pad holder, hold the pad in place.  A rigid handle portion extends up above the skirt, and forms the perimeter of a cavity into which the flattened axial portion of the securing member projects. The outer wall of this handle portion is provided with ridges and grooves to give a better grip to one's hand, which can then place pressure almost directly on the under-lying pad.  Since the pad is forced into a somewhat concave position, the base of the securing member is lifted above the scouring surface and a better scouring surface is provided.

Abstract: Abstract of the Disclosure A modulation control valve includes a modulating valve coupled by spring to an accumulation piston with both fluidly connected to a reservoir valve.  The modulating valve is moved by pressurized fluid in an inlet port connected thereto when a predetermined fill pressure is reached.  The fluid in the outlet port pressurizes the accumulator piston to move it to urge the modulating valve to pressure modulate fluid flow between the in-let and an outlet ports.  Pressurized fluid in the outlet port acts on a return spring end of the reservoir valve to prevent the accumulator piston and on the other end of the reservoir valve from being relieved to a fluid reservoir.  When the accumulator piston abuts the modulating valve, the inlet and outlet ports will be placed in full fluid communication to end modulation.    Sudden demands acting on the modulation control valve reduce the pressure in the outlet port causing the accumulator piston pres-sure to move the reservoir valve to block the spring end of the reservoir valve from the outlet port and allow the accumulator piston pressure to be relieved past the reservoir valve.  When the accumulator piston is relieved, the return spring urges the reservoir valve back to its initial position.

Abstract: ABSTRACT OF THE DISCLOSURE   A ball and socket coupling in which the ball is positively retained within the socket by means of a cap, removably secured to the socket for closing the open end of the latter and having a hole through which the ball stem extends.  The cap hole allows pivotal movement of the ball relative to the socket.  The socket and the cap have inter-engaging interrupted threads for securing and releasing the cap by a simple one-quarter turn of the same.  A lever is pivoted to the cap and engages between ears of the socket in the secured position of the cap to provide a safety lock.  The resulting coupling is much stronger than conventional ball and socket couplings, because the cap forms an abutment faces all around the ball.

Title: Process and device for the production of  aluminium by the electrolysis of a  molten charge
Inventor: TSCHOPP THEODOR M
IPC: C25C3/08
Filed: 1977-05-12
Granted: 1981-12-15
Abstract: ABSTRACT OF THE DISCLOSURE The magnitude of the horizontal components of electrical current flowing through the aluminium on the cathode blocks of an electrolytic reduction cell are reduced by ensuring that the current transmitted decreases towards the edge of the electrolytic cell.  This is achieved by making the contact resistance between the carbon lining and the cathode bars embedded in the carbon cathode blocks increase towards the edge of the cell.  The result is that the tendency for the melt to bulge upwards and the consequent stirring effect, as is the case with known processes and apparatus, is considerably reduced.

Abstract: ABSTRACT OF THE DISCLOSURE A set of manifold business forms includes at least three plies having selected mating surfaces coated with chemicals which are capable of reacting with one another to produce a colored mark  An intermediate ply of the set is of tissue material having its back surface coated with a color precursor in the form of a microencapsulated liquid, and the bottom ply of the set is of an opaque material having its front surface coated with a composition of a generally solid record-developing material.  The top ply of the set is likewise of an opaque material so that, upon the application of pressure to the set, an image is developed on the top surface of the bottom ply.  The use of a coated-back tissue avoids capsular damage during the printing operation of the forms since all that is printed is a coated front sheet.  In another embodiment, a web capable of being zigzag folded is coated on both sides with a composition of a generally solid record-developing material, tissues being interleaved between the folds of the web and having their back surfaces coated with a color precursor in the form of a microencapsulated liquid.  Again, application of pressure to the set develops an image on the top surfaces of each section of the folded web which underlies the tissues.

Abstract: MICROPROCESSOR CONTROLLED ROLL FILM MICROFICHE READER     Abstract of Disclosure An electronically controlled photographic image utilization device is arranged to transport a roll of microfilm having all images printed thereon in separate photographic areas, each area being arranged in a microfiche-type format.  The photographic image utilization device has an automatic call-up feature so that any given photographic area may be selected and projected responsive to the push of a button, the operation of a rotary switch or both.  A special bar code is printed along the edge of the film and used in conjunction with a closed loop film control system to eliminate the need for precise, clock controlled synchronization between the film transport and the code reading.  Preferably, the bar code is read by optical electronic sensors.  Responsive thereto, the electronic control system accurately positions a selected photographic image, on the microfilm, within a viewing area.  Thereafter, and while the film transport is being held stationary, any image on the microfilm may be selected for projection by a manual movement of a single lens positioning mechanism which is small, compact, and easily moved.  The reader may also be operated manually so that the automatic controls may be bypassed, if desired.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure teaches a process for pre-wetting a conducting particle, hydrophobic bonded, substrate supported, gas diffusion electrochemical cell electrode by causing electrolyte to wet the conducting particles in the hydrophobic-bonded portion of the electrode.  The process includes the step of exposing the dry conducting particle, hydrophobic-bonded portion of the electrode to the electrolyte while maintaining the substrate substantially unexposed to the electrolyte.  An external electrical potential is applied across the electrode between the substrate and the electrolyte.  The potential is of sufficient magnitude to increase the rate at which the electrolyte enters and wets the conducting particle portion of the electrode.          The potential is maintained for a period of time sufficient to substantially completely wet the conducting particle portion of the electrode, at which time, the external electrical potential is removed.
